Title: On-vehicle optical disk player
Inventor: YOKOGAWA FUMIHIKO
IPC: G11B33/08
Filed: 1984-01-26
Abstract: PURPOSE:To obtain performance having high resistance to vibration without deteriorating the reproduction capacity against flaws of a disk and their related defects, by detecting the disturbance applied from outside and switching the band of a tracking servo circuit according to the disturbance detection signal. CONSTITUTION:The signal sent from a pickup is amplified by a preamplifier 2 and calculated to obtain a tracking error TE. Here a vibration sensor 8 and a vibration detecting circuit 9 are used to discriminate the external vibration from the internal vibration and detect said vibration. The sensor 8 uses a vibration detecting pickup such as an acceleration pickup attached to a car body, an optical disk player or its attachment member or another type that cuts the optical path of a photosensor reaching a photodetecting part from a light source through a slit. The output of the sensor 8 is amplified by an amplifier circuit 9a of an output detecting circuit 9 and then differentiated by a differentiating circuit 9b. The output of the circuit 9b is compared with a prescribed level by a comparator 9c, and a band switch signal is delivered when the output of the circuit 9b exceeds the prescribed level. Thus the time constant is switched for an equalizer in a tracking servo circuit 5.
